In this unit – 'New shapes can be made by joining (combining) or partitioning (breaking apart) existing shapes', students will learn that:
- two-dimensional (2D) shapes can be made by joining (combining) and breaking apart (partitioning) existing shapes
- shapes have attributes that are necessary for classification as that shape (features of triangles, circles, squares, rectangles)
- necessary attributes are called features
- shapes and objects can be halved in different ways
- new shapes can be created by adding or removing sides
- numbers, like shapes, have smaller numbers hiding inside of them (numbers 0 to 10).
Representing whole number – MAO-WM-01, MAE-RWN-01, MAE-RWN-02
- Instantly name the number of objects within small collections
- Recognise number patterns
- Connect counting and numerals to quantities
Combining and separating quantities – MAO-WM-01, MAE-CSQ-01, MAE-CSQ-02
